I found a couple of sites where some load data for the .375 Taylor (.338-375) have been posted. I remember some data being posted on this forum (reloading Pages). Here is one I found in the Internet:

http://www.geocities.com/bw_99835/375Taylor.htm

The statement that the WSM cartridges are derived from the old .404 Jeffrey is, I think, in error. The various RUM rounds were developed from this parent case, but, the WSMs actually are based on a forgotten case developed by Winchester decades ago, for potential U.S. military use, I think that it was known as the .345 Win. (?)

This case was re-invented as a wildcat by several people over many years. I think that the original specs. for this case came from the blackpowder .50-110 Winchester rounds which were used to develope the .348 Win. The .404 is a rimless version of the original .450 Nitro, itself a re-developement of a blackpowder cartridge.

ON the origin of the wsm line.

since one can make the 404 brass from the rum brass, and one can make the wsm brass from the rum brass, these are obviously in a lineage. (and jamison's line from any of the above)

the 348 was derimmed and worked ovver to make the Heavy Express line of round, the HE Mags. I believe Mr. Hubble, a poster on this board, developed this line, but I could be wrong.

Be that as it may, the 404 is the parant of the rum, wsm, and saum and wssm, rounds...

At least 2 of us on this forum are using a similar wildcat, the 9.3 Brenneke necked up to .375

I am enjoying mine a great deal, and am beginning to experiment with lighter weight bullets for deer.

I chose the Brenneke case only because I don't like belted cases (but I am NOT one of those who worries about accuracy or feeding problems from belted cases...they shoot and feed just fine...I just don't like them).

It is a great moose and bear cartridge.
It's overkill (I know) on whitetails, but I am shooting it so much that I want to keep it with me all season long, hence my playing around with lighter bullets at higher velocities.

first you attack me over if a wsm can feed, and then you say you want one, while insulting me and clobbering me with SOMEONE ELSE"S data...

whew, what a guy

jeffe,
The above quote says it all, you make many assumptions on what I posted earlier(and you are way off as anyone can read). I also think you misunderstood my posts as I was refering to the 375/300WSM wildcat instead of the 30cal on down WSMs. But you know that and would like to twist the subject angle. Yea, I'll back off out of respect for the forum as it's obvious you bit off more than you can chew.

I love that Brennke case too...is not the case head on that one .494 or something in between the '06 and the H&H?

As for the 375 Dakota...that one has broad enough shoulders to get necked up to .416 and will top the 416 Rem Mag by 100 fps in an '06 action.

I think the majic of the 375 Taylor is that the case and head size is so common, and so little work is required to form it, its like falling off a log. I too would prefer it to be beltless, but then we loose the common H&H case head size.

The fun part is, of course, in the shooting...having some familiarity with the 338 Win Mag and launching a 300 grainer out of the Taylor. It is a transformed and totally different rifle!!

Much of this is due to the common sense approach to the construction of most 375 hunting bullets, as they are very short for their weight. Especially when compared to the 338s. The BCs are about 10% lower, but this makes no practical difference in the field.

A 300 gr Woodleigh 375 SP seated to 3.34 COL in the Taylor only needs 0.1565 depth in the neck...the rest is R15.
